Ric does make a 5 string - in limited numbers, and special order I'd guess. Somebody said they saw one in a store in Minnesota. To my knowledge there are no 5 string Ric replacements.

I have a set of Duncan Rics and they are decent pups. Don't know how they compare to original Rics cause they didn't go into a Ric Bass. But I've been told by Ric owners who've made the swap the originals have less output than the Duncans. No comments on tone. From what I've read the Bart replacements are closer to original Ric tone but have that Bartness about them - so not just the same.

But pups pickup the inherent acoustic tone of a bass so even originals will sound different in different basses. I've swapped my Duncans from an acoustically dark bass to an acoustically bright bass and the pups brighten up in the process. And it goes without saying that moving the pups either direction (regarding your routing) will alter the tone considerably. Friend with a 4001 is supposed to be getting me the measurements from the twelfth fret for the pups, but ain't got them yet.

The SD Rics have plenty of treble. There's a review on them under Dimento's HB style experiment. I stuck them there cause the Ric stuff seemed to fit more in a catch-all category than their own. Maybe I'll split it out if I run across more Ric pups.
